Adafruit Ultimate GPS Breakout with GLONASS + GPS - PA1616D
The Adafruit Ultimate GPS Breakout with GLONASS + GPS is an enhanced version of the popular Ultimate GPS, built around the MTK3333 chipset with PA1616D module. It supports both GPS and GLONASS satellite networks, tracking up to 33 satellites on 99 channels for improved coverage and accuracy worldwide.
With -165 dBm tracking sensitivity, up to 10 Hz position updates, and only ~29 mA current draw during navigation, this breakout delivers excellent performance for demanding location projects. It includes external antenna support via a u.FL connector, built-in datalogging, PPS output, and RTC battery backup.
Key Features
- GPS + GLONASS Support – Dual constellation tracking for better coverage and faster fixes
- 99-Channel Receiver – Tracks up to 33 satellites with -165 dBm sensitivity
- 10 Hz Updates – Up to 10 position updates per second for high-speed tracking
- Low Power – Approximately 29 mA current draw during navigation
- 5V Friendly – Built-in 3.3V regulator accepts 3.3–5V DC input with 5V-safe logic levels
- Dual Antenna Support – Internal ceramic patch antenna plus u.FL connector for external active GPS antenna (auto-switching)
- Built-in Datalogging – Logs time, date, longitude, latitude, and altitude every 15 seconds to internal FLASH (approx. 16 hours of storage)
- PPS Output – Pulse-Per-Second signal output on GPS fix
- RTC Battery Backup – Footprint for CR1220 coin cell enables warm starts
- ENABLE Pin – Turn the module on/off via any microcontroller pin or switch
- Fix Status LED – Blinks at 1 Hz while searching, once every 15 seconds when fix is acquired
- Breadboard Friendly – Standard 0.1" header spacing with two mounting holes
Ideal For
- GPS/GLONASS tracking and datalogging projects
- Drone and robotics navigation
- Outdoor and vehicle location systems
- Applications requiring improved satellite coverage (e.g. urban canyons)
- Time-synchronisation applications using PPS output
Package Contents
- 1× Adafruit Ultimate GPS Breakout with GLONASS (fully assembled and tested)
- 1× CR1220 coin cell holder (battery not included)
$GN instead of $GP when both GPS and GLONASS are available. Antenna query commands differ from the classic MTK3339 version — check the datasheet for details.
